An energy deposition of about 1050 erg into exterior 10^{-3} layers of a red giant is calculated to produce an optical phenomenon similar to afterglows of gamma-ray bursts observed. The mechanism can be realized if GRB is generated by some mechanism in a close binary system. If GRB occurs in a close binary system with a more compact massive blue giant, expanding velocities of the shell blown off by a huge flux of hard X-ray illumination will attain relativistic values thus producing phenomena similar to the standard relativistic fireball model.
